Title: Electric Field Assisted Assembly of Perpendicular Oriented NanorodSuperlattices

Abstract

We observe the assembly of CdS nanorod superlattices by thecombination of a DC electric field and solvent evaporation. In eachelectric field (1 V/um) assisted assembly, CdS nanorods (5 x 30 nm)suspended initially in toluene were observed to align perpendicularly tothe substrate. Azimuthal alignment along the nanorod crystal faces andthe presence of stacking faults indicate that both 2D and 3D assemblieswere formed by a process of controlled super crystal growth.

  • Core-shell nanofibers of nickel ferrite and lead zirconate titanate have been synthesized by electrospinning, assembled into superstructure in uniform or non-uniform magnetic fields, and have been characterized in terms of ferroic order parameters and strain mediated magneto-electric (ME) coupling. The core-shell structure was confirmed by electron microscopy and scanning probe microscopy. Studies on magnetic field induced polarization P in assembled samples showed a decrease or increase in P, depending on the nature of fibers and strengthening of ME coupling with change in remnant-P as high as 32%. Strong ME interactions were evident from H-induced variation in permittivity at 20–22 GHz.
  • The average equatorward component of the perpendicular electric field between the dusk plasmapause and polar cap has been determined at seven altitudes below 8000 kilometers by averaging large scale electric field measurements made on 166 passes of the S3-3 satellite through the dusk auroral zone. The observed variation of the perpendicular electric field with altitude and latitude requires the presence of an upward pointing parallel electric field over a latitude range of a few degrees centered near 70/sup 0/ invariant latitude, and with a maximum parallel potential of several kilovolts.
  • The evolution of a plasma with a localized electric field perpendicular to an external magnetic field is shown to be dominated by the Kelvin--Helmholtz instability. For small ion gyroradius, the instability is similar to the fluid mode. When the ion gyroradius is an appreciable fraction of the spatial extent of the electric field, the plasma is not in equilibrium, and the initial drift profile relaxes. Subsequent evolution still leads to vortex flows.
  • The author develops the problem of whistler generation in an infinite magnetoplasma having an ac electric field perpendicular to the field lines, and a plasma distribution function including loss cone particles and temperature anisotropies. Such plasma have been observed in the magnetosphere. The authors consider the effect of electron injection into this plasma on the whister generation, as could result from solar wind interaction with the magnetosphere. They find that the frequency of the ac electric field has a large effect on the instability growth rate, and that the injection of hot electrons can also stimulate the growth rate.
